Firstly you can see my screenshot of my inbox, showing the two received e-mails from the professor:
During this week we had to submit another project, called "secure e-mail". This project was about signing and encrypting e-mails by using Mozilla Thunderbird. I never used this programme before, but I think I am going to use it in the future as it provides a very convenient way to manage your e-mail accounts.
While searching an article about a business using secure e-mails I found an article about Nike. This article is basically about Nike starting to adopt a world wide site license for its WorldSecure(TM) Server in 1999. This is when Nike started to really protect their e-mails. Shortly before, the company recognized that securing e-mails is key to successfully operating over the Internet. "Secure e-mail is key to Nike in order for us to leverage the Internet and Internet mail for communications with hundreds of our trading partners and remote offices around the world," (CEO Tom Beane). In addition to encryption and digital signature, the adopted WorldSecure Server offers Nike the opportunity to protect its entire end-user community and business partners and blocking SPAMs and other unsolicited Internet mail.
